KEY BENEFITS •• IMO Tier III Compliant •• Lowest gas fuel consumption in the industry •• Lowest fuel oil consumption in the industry •• Most powerful 4-stroke gas engine on the market •• Fuel flexibility •• Proven and reliable dual-fuel technology •• Long overhaul intervals •• Low exhaust gas emissions •• Low gas feed pressure •• Embedded automation system The Wärtsilä 46DF is a four-stroke dual-fuel engine that can be run on natural gas, heavy fuel oil (HFO) or marine diesel oil (MDO). The engine can smoothly switch from gas fuel to HFO/MDO operation and vice versa without loss of power or speed. The Wärtsilä 46DF design is based on the well proven and reliable Wärtsilä 46F and Wärtsilä 50DF engine families, which have operated successfully on the market since the early 2000s. Both engines have an outstanding track record, with more than 700 engines in operation and over 9 million running hours experience using Wärtsilä’s leading DF technology. The Wärtsilä 46DF extends Wärtsilä’s dualfuel engine family by covering the power range from 6.2 MW to 18.3 MW at 600 rpm. APPLICATION FLEXIBILITY The Wärtsilä 46DF is designed for a broad range of marine applications. Thanks to its fuel flexibility and the modular, compact design, the engine can be optimized for constant speed diesel electric operation. It also meets the need for direct drive main engine propulsion, operating at either constant speed or along a combinator curve. The multi-fuel operation capability offers new machinery opportunities for various vesse

The switch between fuel types is made without loss of power or speed. The engine automation adapts automatically to the relevant fuel selection, both in normal and emergency modes. In gas mode, the natural gas is fed to the engine at low pressure. This...
